--- Comment #13 from Uroš Bizjak <ubizjak at gmail dot com> --- I assume that memory inputs are not problematic for SSE/AVX {R,}SQRT, RCP and ROUND instructions. Contrary to CVTSI2S{S,D}, CVTSS2SD and CVTSD2SS, we currently don't emit XOR clear in front of these instrucitons, when they operate with memory input.
